Abstract
Spear gun for killing venomous fish is powered by compressed gas such as from SCUBA tank. Spear is attached to a base plate that retains spear partially inside body of spear gun. Discharge of spear gun compresses a spring as spear moves forward, causing spear to automatically return to cocked position after firing. Sliding spear cover makes transport of spear gun safer and helps to dislodge fish from spear.
